Mandatory Versus Incentive-Based State Zoning Reform Policiesfor Affordable Housing in the United States:A Comparative Assessment

To break the chain of exclusionary zoning and produce affordable housing, mandatory state zoning reform policies have been in place for a couple decades in the United States. Their success is often constrained by local resistance and noncompliance. Some scholars argue that the lack of incentives to communities for affordable housing production is one of the main reasons for their resistance to state mandates. At present, no incentive-based state zoning reform policy is at work except in Massachusetts. Inclusionary zoning policies do offer incentives to developers but not to communities. This article examines the strengths and weaknesses of mandatory state policies and Massachusetts's incentive-based policy and offers policy insights for the future.     

An Empirical Study on the Relation Between the Critical Angle for Bullet Ricochet and the Properties of Wood

The properties of a bullet, an object, and the incidence angle determine whether the bullet will penetrate, perforate, or ricochet. In this study, the critical angle for ricochet was established for .32 Auto and 9 mm Luger bullets on Abachi, Southern Yellow Pine, Beech, and Ipe wooden boards. Results show that the critical angle differs depending on caliber and wood type. The critical angle is higher for .32 Auto bullets than for 9 mm Luger bullets and increases with increasing wood density and Janka hardness. The established critical angles for ricochet on the lightest and softest wood (Abachi) are 10.4° and 10.3° for .32 Auto and 9 mm Luger, respectively. For the heaviest and hardest wood (Ipe), the angles were 45.0° and 33.4°, respectively. The combined results on the four tested woods show a strong linear relationship between both the density and the hardness and the critical angle for both calibers.

绿色GDP核算与山西可持续发展

山西经济结构为重型结构,资源与环境问题非常突出。文章通过对山西绿色GDP核算的研究,提出山西可持续发展的对策:树立绿色GDP的理念,转变经济增长方式;建立完善山西资源开发和环境损耗的经济补偿机制;以绿色GDP促进循环经济发展;将绿色GDP纳入干部的考核体系中。     

关于循环经济理论与实践的思考

随着经济快速增长和人口增加,资源不足的矛盾越来越突出。中央宏观调控的一个重要目标就是重塑一个资源消耗低、环境污染少、经济效益好的国民经济体系,为建设资源节约型社会奠定基础。因此,2004年的中央经济工作会议高举发展循环经济大旗,发展循环经济被提到一个前所未有的战略高度。     

The State and Human Rights: Governance and Sustainable Human Development in Yemen

International Relations theory has had difficulty explaining the global spread of human rights norms, and in particular the spread of human rights norms in the non-Western world. An exploration of Yemen's integration of human rights-based approaches to economic development into its policymaking gives the empirical foundation to examine the interplay of both norms and self-interest and external and internal pressures in framing such policies. In the case of Yemen, at least, each of these contrasting pairs is to a large degree mutually constituted. Conceptualizing norms and self-interest and external and internal pressures as mutually constitutive differs from the usual contrasts painted between these pairs in international relations theory, but is an important step in moving beyond an impasse among realist, liberal, and constructivist theories and toward a usefully integrative approach.

《森林法》修改的几个问题

作者提出了《中华人民共和国森林法》修改的基本思路,主张修改后的《森林法》应该成为森林资源法律子体系中的核心法律,林业行业的基本法律,即全面反映当代新型林业和森林资源在我国经济、社会和环境建设中重要地位和全面作用。认为在修改《森林法》时,必须坚持以可持续发展观为指导,体现当代环境资源法的基本理念,在有关问题上与国际法接轨,认真总结和吸收国内有关环境资源和林业的法制建设经验。《森林法》修改应该建立在对森林的性质、特点和作用的科学认识的基础上,针对我国现实存在的森林资源环境问题,突出森林保护和森林生态建设,加强对经济手段和市场机制的采用,加强对公众参与等社会调整机制的采用。
